How do I identify and track panorama photos in Lightroom 3?I do something like this but I use the tags: panorama and panorama part. I then have 2 smart collections for these tags. I too use the stack feature as I can look in the panorama collection, right click to jump to photo in library and then it is in the stack with the panorma parts (regardless if HDR/NonHDR)

Is version control software used for photos?@Tierno - You should be ok with that. I believe any limits experienced are going to be around SQLite constraints which as a developer am sure you can research. (FYI: SQLite Manager for Firefox works great at looking at this catalog)
